To all whom, it may concern.

B'e'i-t known that I, AUG-USIE J. RossI, a

. citizen of the United States, and a resident a specification, my present application for patent belng a division of my pending application, Serial No. 517 ,546','fi led September 14 1909-.

The object of my present invention is to facilitate, economize in, and improve certain metallurgical processes and procedures and their .resulting products, to wit, particularly the incorporation, when required, of silicon and titanium into other metals during manufacture, more especially copper, and, not

only this, but to impart'to the metals, so. treated with titanium and silicon, improved novel properties attributable to my novel procedures hereinafter described.

The beneficial characteristic :efl ects of titanium upon other metals, either as an alloy therewith, or in minute quantities as an eliminator of undesired compounds therefrom, are, by now, well understood; likewise the other characteristic advantages of in.- troducing silicon into such other metals. In some instances I have found it particularly desirable to incorporate, at certain stages,

with other metal, notably copper, botl1;titanium and silicon. These manipulations, and their novel, characteristic, beneficial results, have hitherto, I believe, provided unattain able except by resort to introduction of separate and different charges, the one comprising silicon, and the other titanium, or

of an alloy, or compound, of silicon on the one hand with other metal, and on the other hand of titanium with another metal, silicon being, strictly speaking, a metalloid, but industrially considered as metal, of which it has the appearanceand many pro erti'es.

My researches and experiments 'a-ve demonstrated that it is possible to produce a compound or alloy, of silicon with titanium, comprising also, if desired, copper or other metal, whereby the aforesaid characteristic beneficial effects of silicon and titanium sep arately introduced, and others resulting from their unison, are imparted to other metals for various purposes.

My present invention thus comprlses the.

production, on a commercial scale, and ,for the treatment of other metals industrially, of a new article, being a compound, or alloy, of titanium copper and silicon. My said method also.- includes the proportioning of the constituents in the product to. suit- Patented Apr.16,1912.:

the special requirements of. different. manufactures, it being thereby possible to vary the-respective'silicon and? titanium contents within very wide limits; In fact: thevariation of respective proportions is, by my said method, feasible to suit substantially all industrial requirements.

I; thoroughly mix together white sand (z'. e...practieal1y pure silica), rutile (practically pure TiO and powdered carbon in suitable proportions to insure in the resultingproduct'the respective desired contents of titanium and silicon according to the formulae i That is: 24 carbon tor 60 silica and 80 rutile'.

Sr 60 Ts-Slllfifi. T1 0x60 of T10 Omitting the fractions in the atomic weights, and taking (1:12; Ti=48; Si-=28; 0:16. This is at the-rate of 0.40" carbon for 1 silica (8e01,). 01.30- carbon for 1 titanic acid (TiO My mixture having been prepared as above stated, the next step is'to charge it into a furnace or other container constructed, and. provided with means, to raise the charge to a temperature suficiently high to insure reduction oil the oxids by the carbon and subsequent withdrawal for use of the resulting. molten alloy or compound of silicon and, titanium in elemental state. I have found it preferable touse for this purpose an electric furnaceof any approved type,

:No. 892,941, granted to me on October 2%, 1-968 for process for the reduction of metallic oxids, etc., but it is, of course, to be understood that I, do not confine myself to this particular method of supplying the requ1red heat to the charge, and that any apparatus adapted to produce and maintain sufiiciently' long atemperature adequate 'to reduce, by. carbon, all of the SiO, and TiO, in the Within said central cavity, the cathode, a

carbon electrode'is vertically movably supported and means supplied for imparting thereto such vertical motion. The electric current may be turned on by sufliciently lowering said anode, thus bringing it into there or required approximation to the cathode, whereupon the said mixture is charged in around said anode. The required reaction then sets in, resulting finally in entire reduction of the SiO and TiO by the carbon to metallic state.

-I incorporate into the silico-titanium, while being produced by my said method as above illustrated, a proportion of an additional metal, as for instance copper, when said silico-titanium is designed for the treatment of copper, thus producing an alloy or compound of copper,.silicon and titanium in desiredproportions, which may be termed a cupros'ilico-titanium. In many instances such addition of the copper appears to facilitate or otherwise favor the desired re- 40" duction of the oxids of titanium and silicon.

' If, for instance, there be added to the said mixture 20 lbs. of copper and the charge subjected to the temperature above de scribed, or even a lower temperature, a resulting" metallic product, alloy, or compound, will be obtained, containing Gopper 20 lbs. or Cu 16.66+

Sil1con 70 lbs. in Si 5833+ Ti 30lbs. 25.00

120 lbs. 100.00

p In lieu ofmetallic copper, its oxid CuO, or any other oxid of copper, may be similarly added .to, the mixtureof silica and titanium oxid in such proportions as to yield, by its reduction, by required increased amount of carbon in the charge, a quantity of copper equal to 16.66 lbs. of copper, according to formula The presence of the aforesaid cupric content in the mixture appears not only to facilitate the desired, reduction of the silica and titanic acid, but it also appears'to impart to the resulting product properties useful for certain purposes, as for instance greater fusibility, or capacity for dissolving, on said resulting products being added thereafter to copper in ordinary manufacture for the purpose of improving the same and imparting thereto the characteristic effects of silicon and titanium.

Without departingv from my invention,

instead of carbon, any other reducing agent. might be employed com etent to reduce the oxids mentioned.

What I claim as new and desire to secure by Letters Patent is the following, viz

1. As a new article of manufacture an alloy, or compound, of copper, silicon and titanium. I u

2. The aforesaid method for producing an alloy, or compound, of copper, silicon and titanium, WhlChCOlIlPIiSQS bringing together, in desired proportions, a. cupric material, oxid of silicon and oxid of titanium,

and a reducing agent, and subjecting them to a temperature\sufiicient to reduce the oxids and produce as a resulting product the said alloy or compound.

'3. The aforesaid method for producing an alloy, or compound, of copper, silicon and titanium, which comprises bringing together, in desired proportions, copper, oxid of silicon and oxid of titanium, and a reducing agent, and subjecting them to a temperature sufiicient to reduce the oxids and produceas a resulting product the said al- 10y or compound.

4. The aforesaid method of producing an alloy, or compound, of copper, silicon and titanium, which comprises bringing together, in desired proportions, copper, oxid of silicon and oxid of titanium, and carbon, and subjecting them to a temperature sufiicient to reduce the oxids and produce as a resulting product the said alloy or compound.
